Definitions

  • the invention relates to a height-adjustable base of a motor vehicle seat with a left and a right pair of rails Lijnsverstellvorraum and with a left and right side part, which are each connected via a rear and a front pivot arm with the associated seat rail of the rail pair.
  • Height-adjustable bases of this type are known in many designs. Each seat side constitutes a four-bar linkage. This is adjusted and found by making a joint adjustable and lockable, for example by means of a dental arch concentric with the joint and a pinion engaged with this dental arch. The setting and detection can be done via a drive, usually electric motor, or manually. From the DE 198 27 067 C1 is a height-adjustable base of a motor vehicle seat according to the preamble of claim 1 known. It is anxious to arrange the adjusting and locking device on the side part. As a result, it always remains in the same position with a manual operation to a passenger.
  • the aim is not to position the adjusting and locking device too far back, in particular not in the area below a backrest of the motor vehicle seat, but more forward to arrange the seat front edge. It is thus easier to reach for a passenger.
  • the invention is based on these considerations. It has made it its mission to further develop the base of a motor vehicle seat of the type mentioned in that the locking device that provides for setting and locking, quite far forward, at least preferably can be arranged in front of the longitudinal center of the side panels. This opens up the possibility of saving space in the rear area of the seat, below the backrest.
  • the controls for the locking device can be arranged conveniently.
  • this object is achieved in that a blocking arm is provided which is articulated with a lower end portion at the hinge point of a rear pivot arm on the associated seat rail and which is releasably fixed in the vicinity of its upper end in a locking device , which is attached to the associated side part.
  • the blocking arm runs almost on a diagonal in the four-bar linkage, which is formed from the seat rail, the rear pivot arm, the side support and the front pivot arm.
  • the four-bar linkage is significantly stiffer in the locked state than in blocking only one of the four joints.
  • the locking device can be arranged at different locations of the side part, while you can achieve a position for manual adjustment manual handle, even for a motorized setting can find an optimal position. You are free of the actual pivot point, so it saves space or can use the space elsewhere.
  • the blocking arm has a toothing in the region of its upper, front end and the locking device has a pinion rotatably mounted in the associated side part. That way is achieved with simple means a very easy-to-use and safe blocking locking device.
  • the upper, front end of the blocking arm can be designed as a spindle and the side part a rotatable nut is set, which receives this spindle.
  • the locking device is arranged in the vicinity of the hinge point of the front pivot arm on the associated side part. This results in a relatively large support length through the blocking arm. Furthermore, it opens up the possibility to arrange front and rear pivot arms of the seat side in a plane and to attach the blocking arm in a staggered to her level.
  • the blocking arm is thereby a flat part. It runs parallel to the associated side part.
  • the blocking arm has a guide surface opposite its toothing. It is provided a guide member which is fixed to the pinion opposite to the associated side part. In this way, the blocking arm between pinion and guide part is guided. This results in a functional and practical training. This is further developed by advantageous that the upper end of the blocking arm is embraced annularly in the region of the locking device.
  • the height-adjustable underframe has a left pair of rails 20 and a right pair of rails 22, which together form a Leksverstellvorraum. Furthermore, the base frame has a left side part 24 and a right side part 26.
  • the rail pairs each consist of a bottom rail, which is attached to a bottom group of a motor vehicle, not shown, and a seat rail.
  • the seat rail is connected to the associated side part 24 or 26 in the rear region of the undercarriage via a rear pivot arm 28 and in the front region via a front pivot arm 30. As a result, a four-bar linkage is formed.
  • the front pivot arm 30 may be composed of two individual arms, which have their own adjustment. In this way, the height of the front edge of the undercarriage can be adjusted separately.
  • the two rear pivot arms 28 are rotatably connected to each other via a cross member 32.
  • the two front pivot arms 30 have no direct connection analogous to the traverse 32. Although such can be provided, but in principle is not necessary.
  • the left side of the undercarriage which appears in the figure on the right, has a device for adjusting the height of the side part 24 relative to the pair of rails 20. This device will be discussed in more detail below.
  • a blocking arm 36 is articulated. This articulation is carried out at a lower, rear end portion of this blocking arm 36.
  • the blocking arm 36 extends substantially on a diagonal of the four-bar linkage of the two pivot arms 28, 30, the seat rail and the left side part 24th
  • a locking device 38 is provided on the associated side part 24.
  • it has a pinion 40 which is rotatably mounted about a pinion axis in the left side part 24. It stands on the inside of this side part, which faces the other side part 26 before.
  • an input and locking device On the outside of this side part 24 is an input and locking device, which is manually operated here in the illustrated embodiment. The operation takes place via a hand lever 42.
  • so-called stepping mechanisms are used, as for example DE 36 08 858 A .
  • DE 44 00 910 A and DE 36 16 290 A are previously known.
  • the hand lever 42 is in the rest position. If it is pulled upwards within the permitted swivel angle, the pinion 40 rotates in one direction. If the hand lever 42 is pressed down, the pinion 40 rotates in the other direction.
  • a toothing 44 is provided which is in constant mesh with the teeth of the pinion 40.
  • the blocking arm 36 has a guide surface 46, which runs parallel to the toothing 44.
  • This guide surface is associated with a guide member 48 in the form of a stud.
  • the guide surface 46 slides on this guide part 48. It is possible to make the guide part 48 elastic, so that it preloads the guide surface 46 and thus the blocking arm 36 elastically with respect to the pinion 40.
  • the bearing axis of the pinion 40 and formed as a bolt guide member 48 are connected by a termination member 50 with each other. Since the guide member 48 and the pinion 40 are disposed on the left side portion 24, a closed, annular wrap around the front, upper end portion of the blocking arm 36 is achieved.
  • the blocking arm 36 has at its free end a nose 52 which jumps away from the guide surface upwards. In an alternative, a nose may be provided which jumps downwards from the toothing 44.
  • the nose 52 is dimensioned such that the free end region of the blocking arm 36 does not fit through the gap between the guide part 48 and the pinion 40. In this way it is avoided that the blocking arm 36 can come out of engagement with the pinion 40.
  • the left front pivot arm 30 is hinged to the inside of the left side part 24, this articulation is about a pivot axis 54. It is located in the immediate vicinity of the guide member 48 and slightly above the pinion 40.
  • the front pivot arm 30 is as executed flat part which is plastically deformed in its lower region, but not in the region of the overlap with the side part 26.
  • the free end of the blocking arm 36 engages over and covers the upper region of the front pivot arm 30 on the inside of the undercarriage.
  • the upper front end portion of the lock arm 36 is positioned laterally between the front swing arm 30 and the end portion 50.
  • the blocking arm 36 is made in one piece. In the illustrated embodiment, it has two angularly arranged portions, which enclose an angle between 120 to 160 °. As a result, in the position shown, a front portion which encloses the teeth 44, substantially parallel to the side part 26. A rear portion is at an angle of approximately 45 ° to the pair of rails 20th
  • the blocking arm 36 is a flat stamped part.
  • the blocking arm not at the pivot point 34, but on the rear pivot arm 28, for example, to the crossbar 32 to steer, or to steer it to the seat rail of the rail pair 20 separately, z. B. something in front of the hinge point 34th
  • the pinion 40 is below the toothing 44. It is also a reverse arrangement possible, in which the toothing 44 is formed on the upwardly facing narrow surface of the blocking arm 36. Then the associated guide surface points downwards.
  • blocking arm 36 and associated locking device 38 are located on the seat side to which the buckle is not attached.
  • the right side of the seat has a tab 56, which is provided for the attachment of a buckle via an intermediate piece.
  • the buckle is located on the tunnel side of a motor vehicle. This is the inventive adjustment and locking device for the height adjustment on the outside of the seat, so the door facing side.
  • An electromotive training can accordingly DE 195 23 136 A be realized there, in particular Figure 2. It is also a spindle drive possible, as he, for example, from DE 199 56 614 A is known. For this purpose, the front, upper end of the blocking arm 36 must be designed as a spindle.
  • a blocking arm 36 is provided on both sides of the seat, which engages in a pinion.
  • the two pinions are rotationally connected. Only one pinion is associated with a locking device.
